Important note
Warning
In order to ensure the reliable performance of the
equipment and the safety of the user, please observe
the following matters during the process of
installation, use and maintenance:
The matters needing attention of installation
◆
The power plug shall be handled for easy
disconnection, and the disconnect coupler on the front
panel shall also be maintained for easy disconnection.
◆
The device must not be exposed to water droplets or
splashes, and no objects filled with water, such as
vases, should be placed on the device.
◆
Please do not use this product in the following
places: the place of dust, soot and electric conductivity
dust, corrosive gas, combustible gas; the place
exposed to high temperature, condensation, wind and
rain; the occasion of vibration and impact. Electric
shock, fire, wrong operation can lead to damage and
deterioration to the product, either.
◆
When processing screw holes and wiring, do not let
metal chips and wire ends fall into the ventilation
holes of the controller, which may cause a fire, fault
and incorrect operation.
◆
When the installation work is over, it should be
assured there is nothing on the ventilated face,
including packaging items like dust paper. Otherwise
this may cause a fire, fault, incorrect operation for the
cooling is not free.
◆
Should avoid wiring and inserting cable plug in
charged state, otherwise it is easy to cause the shock,
or electrical damage.
◆
The installation and wiring should be strong and
reliable, contact undesirable may lead to false action;
◆
For a serious interference in applications, should
choose shield cable as the high frequency signal input
or output cable, so as to improve the anti-jamming
ability of the system.
Attention in the wiring
◆
The equipment shall be connected to the grid power
output socket with protective grounding connection.
◆
Only after cutting down all external power source,
can install, wiring operation begin, or it may cause
electric shock or equipment damage.
◆
This product grounds by the grounding wires. To
avoid electric shocks, grounding wires and the earth
must be linked together. Before the connection of
input or output terminal, please make sure this product
is correctly grounded.
◆
Immediately remove all other things after the wiring
installation. Please cover the terminals of the products
cover before electrification so as to avoid cause
electric shock.
Matters needing attention during operation and
maintenance
◆
Please do not touch terminals in a current state, or it
may cause a shock, incorrect operation.
◆
Please do cleaning and terminal tighten work after
turning off the power supply. These operations can
lead to electric shock in a current state.
◆
Please do the connection or dismantle work of the
communication signal cable, the expansion module
cable or control unit cable after turning off the power
supply, or it may cause damage to the equipment,
incorrect operation.
◆
Please do not dismantle the equipment, avoid
damaging the internal electrical component.
◆
Should be sure to read the manual, fully confirm
the safety, only after that can do program changes,
commissioning, start and stop operation.
◆
The button battery must be replaced during a power
outage. It is indeed necessary to replace it with
electricity due to the consideration of the operation of
the equipment, and it needs to be carried out by
professional electrical technicians wearing insulating
gloves.
Matters needing attention in discarding product
◆
Electrolytic explosion: the burning of electrolytic
capacitor on circuit boards may lead to explosion.
◆
Please collect and process according to the
classification, do not put into life garbage.
◆
Please process it as industrial waste, or according
to the local environmental protection regulations.
